AP4.9 bit
4 channel amplifier featuring
9 channel built-in processor.
AP4.9 bit amplifier was designed for the Integration into OEM front/rearsystems where a lot of power is required. The built-in processor, that thisamplifier shares with the AP8.9 bit, provides the ability to assign the pre-outs to theAP1 D amplifier to drive a subwoofer, to the AP4 D amplifier to have 4 additional amplified
channels exceeding 1080 W @ 4 - 2 Ω total power.
